WadC is a functional programming language for the composition of
Doom-format maps. Originally created by Wouter "Aardappel" van Oortmerssen,
I was granted permission to take over the project over a year ago, but didn't
get around to releasing anything until now.

This version adds a few functions that permit you to draw two-sided lines which
are textured and impassible: important for a lot of detailing techniques. You
can also create friendly monsters for Boom-compatible ports. There's a new
example demonstrating these features; plus a recreation of Doom 2's "entryway",
